I Be it knoyvn that I VERI TA BnLIJs'B'RooK,

citizen of the United States, "residing at Bridgeport in the county of Wise and State of Texas, have invente'd-."certai'n 'n'evV' and useful Improvements in' Sheet Placing chines, ofwhich the following is 'a's'peci'fi'c'a- I tion. I u This invention relates to new and useful 1e improvements in pushing' a-nd pulling. de-

vices and which is particularly adapted fer placing sheets of metal in their cor ecerelationship upon oil. tanks for forming. the roofs thereof; V i j An important object of theinventi'oni isto provide a device of the abovenatu're which is constructed in a manner whereby it may be easily manipulated from a'point'adj'acent theside of the tank so that the worker' may operate the device and correctly position the sheets Without fear ofinjury. v

Another object of the inventi'onis' to provide a pushing and "pulling implement the arrangement ofthe parts beingsuch that the object adapted to be adjusted thereby myrbe shifted both longitudinally and later- .ally of the device. f v K i A further object of the inventionis' to provide an implement of the alo'o've nature including a pair of relatively adjustable members one of which is equipped 'With means for shifting the other in 'either direction.

Other objectshand advantages of the inv'ention Willbecome apparent duringithe course of the followingv description; I

Furthermore, the old method 'of'pos ition'ing the h fi exposes the mechamcs to"-increased Q liability of becoming-injur d I v l/Vith my present devicey'placement of the sheetsof steel becomes an' easy *matter and -may be effected accurately, quickly and Without the possibility of the mechanics loecoming injured- InthedraW-ings wherein I have illustrated the preferred embodiment of my invention, the numeral 5design'at'es an' oil tank, approximately one-halfthe top p The upper'rim by the numeral 6 of Whichis I shown iii-Fig. of the tank-is indicated" "and is-provided With plurality or spaced apertures 7 for theinsertion of rivets "a'svi ill be more clearly pointed out hereinaften A= plurality of sheets of metal 8' o'fmor'e' orle'ss triangular-form are provided to form the top of the-tank by positioningthem" so that their apices meet at a" central point 9 and the edges of the plates opposite'the apices rest upon the rim 6* of the'taiik. The three mar- 'gi'nal edges ofeach sheet of metal are provided with a pluralityof spaced apertures 10 which are for the purposeof-rece'iving rivets for securing the plates upon the top of tlie- 'tank." p I My invention consistsin the provision of a't'ool for properlyfan'd easily positioning the" various sheets and-embodies a pair'of 'rslat'ivelymovable members 11 and 12. The I .alembe'r '11, I will designate a theanchorinjg member 'Wlii'cli' coi'l'slsts of an" elongated bar 1 having its intermediate portion provided with a1 1'o'fi'set-"1 3 vvhich provides a depress'i'onf or reeessin the upper f'aee'Lo-f the member.) The outer end 1430f" this anchoring member is provided with an" integral loop as clearly s'eemand from the marginal edges of a said loop-depend apair'of anclioring'plns 15 "as clearly seen in Fig. 4;;

V operating 16%?" isaadapte'd to be 'thewell known manner,-

seated and pivoted within the offset portions 13 of the anchoring member in a manner that both ends of the lever project beyond opposite sides of the anchoring member. However, as clearly seen, one end of the lever forming the handle of the device extends further to one side of the member 11 than the other end of the lever so that the handle will be disposed adjacent the rim of the tank in a convenient place for the mechanic to operate the device. To this operating lever upon opposite sides o-f'the. anchoring member are pivoted a pair of crescent shaped pawls 17 the free ends of which are offset from the planes of the pawls for a purpose which will become obvious. Secured to the lever beyond each pawl are spring contained casings 18 through the inner relative end of each of which mounted a pawl engaging element 19 which is normally urged into engagement with its respective pawl bymeans of a coil spring surrounding the element within the casing and bearing against one endof the casing. The end of each pawl engag'ng element is arcuated as clearly seen in Fig. 3 and the pawl-engaging element being rotatable may be reversed or shifted to engage its respective pawl at either side of the pin pivoting the pawl to the operating lever;

The member cooperating with the anchoring member and which is longitudinally adjustable therealong, consists of an elongated bar 12 having rack teeth 20 disposed along opposite longitudinal edges thereof for cooperation with the pawls 17. The member 12 at opposite ends thereof is providedwith guides 21 which in the present instance form integral oppositely disposed fingers which are bent up and over the anchoring member 11. However, it is to be noted that the engagement of the guide means 21 with the anchoring member is such as to permit the member 12 to freely slide upon the member 11. The outer end 22 of the adjustable mem- 'ber 12 is bent to extend at approximately right angles and is arranged in the same plane with the member 12. The terminal of this angularly disposed end is equipped with a loop 23 corresponding with the loop the anchoring member and is provided with a pair of depending integral pins 24; adapted for the reception in the openings along the edges of the sheet steel plates 8. P

From the foregoing description,- it will. be seen that when the pins 15 of the anchoring member are inserted to a pair of the openings '7' in the rim of the tank and the are associated with a pair of openings in one of the sheets and the operating lever 16 reciprocated in the two members 11 and 12 will move longitudinally. If the pawl engaging elements 19 are disposed in the position shown in Figs. 1 and 3, the

pawls will be caused to engage the rack will be obvious that the sheet 8 will. be

shifted until its apex meets the apices of the other plates at the point 9. Should it be desired, to shift the sheet 8 laterally to ward its adjacent sheet, it will be obvious that one of the pins 15 of the anchoring member may be disengaged from its opening in rim and the entire device swung upon the other pin 15 as a pivot which remains in engagement with the rim of the tank. Should it be desired to shift the sheet outwardly of the rim of the tank, the two pins 15 of the anchoring member are again engaged with the opening in the rim and the pawl engaging elements reversed to cause the ends of. the pawls adjacent the loop 14 to engage with the rack and upon reciprocation of the operating lever shift the member 12 outwardly upon the anchoring member 11. v

The foregoing description vand accompanying drawings have reference to what might be considered to be the approved or preferred form of my invention. I desire it to be understood that I may [make such changes in the construction, combination and arrangement of parts, etc., as may prove expedient and fall within the scope of the appended claims.
